Davis wants to buy 9 bars of chocolate but is short of $ 2.50
If he buys 2 bars of chocolate he will have $5.20 left. How much does each bar of chocolate cost?
Okay, let's break this down step-by-step:
1. Davis wants to buy 9 bars of chocolate but is short $2.50.
2. If he buys 2 bars of chocolate, he will have $5.20 left.
To find the cost of each bar of chocolate, we need to:
1. Calculate the total cost of 9 bars of chocolate
2. Calculate the total cost of 2 bars of chocolate
3. Use the difference to find the cost of each bar
## Step 1: Calculate the total cost of 9 bars of chocolate
* Davis is short $2.50, so the total cost of 9 bars must be $2.50 more than he has.
* Let's call the cost of each bar 'x'
* Total cost of 9 bars = 9x
* Total cost of 9 bars = $2.50 more than he has
* So 9x = Amount he has + $2.50
## Step 2: Calculate the total cost of 2 bars of chocolate
* If he buys 2 bars, he has $5.20 left
* So the total cost of 2 bars must be the amount he had minus $5.20
* Total cost of 2 bars = Amount he had - $5.20
## Step 3: Use the difference to find the cost of each bar
* Total cost of 9 bars - Total cost of 2 bars = Cost of 7 bars
* 9x - (Amount he had - $5.20) = 7x
* Solving for x, we get x = $0.80
Therefore, each bar of chocolate costs $0.80.
